Alex Mensing of Pueblo sin Frontiers, rear, worked his way down the line taking a head count of a group of about 48 Central American refugees lined up to enter the US on Thursday morning, behind another group of 23 that had already presented themselves to immigration officials.

At least 70 more members of the Central American migrant caravan led by the group Pueblo sin Fronteras crossed in to the US Thursday morning, leaving approximately 70 more waiting in Tijuana. Organizers were hoping to start crossing those in to the US in groups of 20 later in the day Thursday but expecting them to be turned back until a later time. In the meantime, those waiting passed their time in the makeshift camp of tents and tarps on the Mexican side of the border.
